Why didn't you quote the entire statement? Here it is in full:
We were most excited for healthy coral reefs, the Picasso-like mandarin fish and blue-ringed octopi – but the crowning glory of this place are the ethereal thresher sharks that grace Monad Shoal in the early mornings. Ideally, our participants needed at least 30 logged dives with deep (30 meters) and night diving experience. But for the ones who didn't,
Evolution helped organize extra training for deep and night diving so that they didn't miss out!
Here is what you wrote earlier:
Some liveaboard operations even require at least x (30, 50) dives below 30 meters to do rec deep dives.
The review you cite does not remotely refer to a
requirement of "at least x (30, 50) dives below 30 meters to do rec deep dives."
Not even close. It says that "ideally" divers should have "30 logged dives" (which is barely anything) and an
unspecified amount of experience going
to 30m, not 50 dives
below 30m. That quote could be accurately rewritten as "Ideally, you should have at least 30 logged dives with some night dives and some dives to 30m, but if you don't, no worries--they'll make sure you get the training you need for that." I see that as inviting pretty much anyone with any experience to do the trip.
EDIT: After writing this, I realized your problem with it might be related to English not being your primary language. You might have understood the phrase "at least 30 logged dives with deep (30 meters) and night diving experience" as requiring 30 deep dives, but that is not what it means. It means that ideally you should have 30 total dives, and those 30 dives should include some night and deep dives.
